Querying Information About Used Space in a Bucket

Functions

This operation queries the number of bucket objects and the space occupied by the objects. The size of the object space is a positive integer, measured by bytes.

The OBS bucket storage statistics is measured in the background, and the storage data is not updated in real time. Therefore, you are not advised to perform real-time verification on the storage information.
